Pesticide spraying device with controllable dosage

Abstract

The invention relates to the field of pesticide spraying devices, in particular to a pesticide spraying device with controllable dosage. The pesticide spraying device with controllable dosage includesa box body, a sealing structure, a pressing structure, a dosage regulating structure, an inflation structure and a pressure releasing structure, wherein external air can be filled into the box body through the pressing structure in a pressing mode, so that the air pressure inside the box body is increased, and pesticide inside the box body is sprayed in a form of mist; through combination with the dosage regulating structure, the dosage of the to-be-sprayed pesticide is controlled precisely, excessively sprayed crops in an area are avoided, and damage to the crops is avoided; through arrangement of the inflation structure, the external air can be squeezed into a secondary box under the action of the wind force in the case of large wind, so that the air pressure inside the secondary tank is increased; and the pesticide inside the secondary tank can be sprayed out without manpower, so that the labor force is saved.

Description

technical field [0001] The invention relates to the field of pesticide spraying devices, in particular to a pesticide dosage controllable pesticide spraying device. Background technique [0002] Pesticides refer to chemical agents used in agriculture to prevent and control plant diseases and insect pests and regulate plant growth. Widely used in agricultural, forestry and animal husbandry production, environmental and household sanitation, pest control and epidemic prevention, industrial product mildew and moth prevention, etc. There are many varieties of pesticides, which can be divided into insecticides, acaricides, rodenticides, nematicides, molluscicides, fungicides, herbicides, plant growth regulators, etc. according to their uses; they can be divided into minerals according to the source of raw materials. Source pesticides (inorganic pesticides), biological source pesticides (natural organic matter, microorganisms, antibiotics, etc.) Esters, amides, ureas, ethers, ph...

AI Technical Summary

Problems solved by technology

[0003] However, the traditional pesticide spraying device generally dilutes the pesticide directly inside the barrel during use, and then directly sprays under pressure. It cannot spray quantitatively for each area, and the spraying amount is not easy to control. And in the case of strong wind, it is more difficult to pressurize due to the resistance of wind force
